Data transmission method for wireless access system, base station, relay station and wireless access system

Abstract

The invention discloses a data transmission method in a wireless access system, which comprises that a base station directly sends control information to a mobile station and / or a relay station; the mobile station and / or the relay station transmits corresponding data to next hop according to the control information until the data is transmitted to a target station. The invention also discloses a base station, a delay station and a wireless access system which use the data transmission method in the wireless access system. The method of the invention can effectively realize peer-to-peer communication between the mobile station and / or the relay station, can flexibly select an optimal transmission path so as to achieve load balancing, and can effectively overcome the problem of traffic bottleneck and transmission delay at the base station in the prior art, and meanwhile, can still guarantee the management control function of data transmission by the base station.

Description

technical field [0001] The present invention relates to wireless access technology, in particular to a data transmission method of a wireless access system, a base station, a relay station and a wireless access system using the method. Background technique [0002] The IEEE802.16j multi-hop relay task group is a working group established by IEEE in March 2006. Its main purpose is to define the multi-hop extension of IEEE802.16 in order to further increase the throughput of the system and expand the coverage of the system. This task group enhances the IEEE802.16e standard by applying multi-hop relay technology between the base station (BS) and mobile station (MS), and defines the systems and functions of the physical layer and MAC layer that support multi-hop relay. [0003] However, peer-to-peer communication is not supported in IEEE802.16j. Peer-to-peer communication is a communication model in which each party to the communication has the same capabilities and each party ...
